Answer:
Identity element property
Step-by-step explanation:
The property that justifies the step 3 is the identity element property.
Mathematically, the identity element is that number such that performing an arithmetic operation such as addition or multiplication with the number gives back the number we started with
For addition, the identity element is 0
while for multiplication, the identity element is 1
Step-by-step explanation:
5x – 2x + 7 – x = ?x + ?
I need the answer for "no solution" and "infinite solutions".
NO SOLUTION:
no solution because any value you give to x is not solvable, it remains +7
5x – 2x + 7 – x = ?x + ?
2x = 2x + 7
INFINITE SOLUTION
infinite solutions because any value you give to x is solvable
5x – 2x + 7 – x = ?x + ?
5x – 2x + 7 – x = 2x + 7
2x + 7 = 2x + 7
In a 45-45-90 triangle, both of the legs have the same length and the ratio of one leg to the hypotenuse is 1:sqrt(2).
